firiginal application filed January 24, 1911, Serial No. 604,409. Divided and this application filed July 22, 1812. Serial No. 710,932.

To all whom it in (13 concern:

Be it known that 1, CHARLES F. Home HART, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improve merits in ShoeDressing-Applying Machines; and I do hereby declare the follow ing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to shoe dressing applying mechanisms and has for an object to present a division of application rial Number 604,409 filed January 24th, 1911, directed to the matter divided out from said application and such as employed for applying dressing to and insuring it being applied to the correct or desired por tion of the shoe being operated upon.

A further object of the invention is to provide means for simultaneously applying dressing to the sides of the vamp of the shoe only and also to the top of the vamp, with means for protecting the upper from receiving the dressing.

\Vith these and other objects in view the invention comprises certain novel constructions, combinations and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawings :-Figure 1 is a transverse sectional view through the structure. Fig. 2 is a view of the structure in side elevation. Fig. 3 is a view in side elevation of a portion of the timing mechanism adapted to actuate the several parts in timed relation. Fig. 4 is a view in vertical transverse section through the timing mechanism, taken on line 4-4 of Fig. Fig. 5 is a transverse sectional view through the top applying means. Fig. 6 is a top plan view of the air-controlling valves with parts of the housing broken away. Fig. 7 1s a tional view through one of the valves and its operating mechanism as indicated by line --7 of Fig. 6. Fig. 8 is a sectional view of one of the valves and its operating mechanism taken on line 8 8 of Fig. 6. Fig. 9 is a sectional view of the valve operating shaft and cams on a plane indicated by line 9-9 of Fig. 6. 10 is a sectional view through the valve housing as indicated by line id-"10 of Fig. Fig. 11 is a sectional view of the valve operating mechanism on a plane indicated by line 11-11 of Fig. 6. Fig. 12 is a vertical sectional view through the machine indicated by line 1*212 of riage 10 has mounted thereon atomizers 12,

and a valve housing 13 with communicating and operating devices as will be hereinafter more fully described. The discharge end of the atomizer indicated at 14 is directed into and through a housing 15, the upper part or wall of which is properly located to correspond substantially with the top of the vamp of a shoe so that the spray of dressing, indicated at 16, discharged from the atomizers 12 is prevented from striking the shoe except at such points as it is desirable for the dressing to be applied to. Above the shoe rest 17 upon which the shoe 18 rests when inoperation a reservoir 19 is located having a discharge nipple 20 n the under side controlled by a valve 21 discharging in the rear of a baille plate 22. The valve 21 is controlled by a valve stem 23 and is held normally closed by a spring 24. For actuating the valve a rock shaft 25 is journaled within the housing and provided with an arm 26 hearing against the valve stem 23 and adapted when the shaft 25 is rocked to open the valve 2]. To rock the shaft 25 a second arm 27 is provided engaged by a rod 28 extending downwardly to a lever mounted to oscillate upon a shaft 30. To oscillate the lever 29 a shaft 31 is journaled adjacent the shaft and provided with a cam 32 proportioned to engage under the nose 33 of the lever 29 and raise such nose and thereby depress the arm 27 and cause the arm 26 to open the valve 21.

To move the shaft 31 to bring the cam 32 into operation a lever 34 is journaled upon the shaft 31 in the ath of movement of stops 35 and 36 carried upon the carriage 10. To retain the lever 34 yieldingly at either extreme of its movement springs 37 are employed. pivoted to the lever 34 upon the pins 3N and 3!) so that the tension of said springs passes beyond the fulcrum of the shaft 31 at each oscillatory movement of the lever. The lever 34 carries. with it an arm 10 which in turn carries a detent 41 engaging a ratchet wheel Hcarricd upon the sleeve -13 to which the cam wheel 3:! is rigidly secured. It is therefore obvious that at each reciprocation of the carriage 10. the lever 34 will be oscillatedto advance the ratchet 42 the distance of one notch so that the shaft 31 will be completely rotated only at the completion of a number of reciprocations equal to the number of notches. To prevent backward motion of the ratchet wheel -12 a detent H- is provided operating in the usual well known manner. To vary the amplitude of movement of the. lever 34 and to limit its movement, screws -15 and -16 are employed against which the lever strikes at the forward and rearward limit of its movement, as apparent especially from Fig. 3. 7

To prevent the rapid action of the lever 34 a dash pot cylimler 47 is employed with a piston is therein connected by a piston rod H with the lever 2H but forming a part of an application filed on even date herewith for the timing mechanism. The element which is shown at Fig. 15 screw-threaded into the top of the dash pot 47 has no function whatever except to permit the introduction of liquid if desired into the cylinder to act in conjunction with the cylinder and piston to produce a dash pot of greater resistance than is pr duced by air alone. Air is ad mitted through the valve housing 13 to the atolnizers 12 by the timing mechanism shown at Figs. 43 to 11 inclusive.

The structure hereinlwforo referred to as the valve 13 comprises in fact two valves 50 and 51 carried respectively upon valve stems .72 and .33. Air from the pumps 54 is conducted through the pipes to the housing of the valve 13 at each reciprocation of the carriage 10, and from the housing of the valve 13 is controlled by the valves 50 and 51. \Vhen the valve 51 is open the air passes from the housing of the valve. 13 through the passage 56 to the atmosphere and by reason of the size of the pipes and passages offers but little, if any, resistance to the. free escape of the air from the pumps 54. \Vhen the valve 51 is closed and the valve 50 is open, passage to the atmosphere is interrupted and escape from the housing of the valve 13 is then provided through the passage 57 and pipes 58 to the atomizers 1-1 a shown more particularly at Fig. 1. y

To operate the valves 50 and 51 in proper timed relation t the operation of the valve 21 shown at. Fig 5, a shaft 59 is journaled adjacent the valve stems 52 and 53 and provided with cams 60 and 61 in alinement with such valve stems and adapted to actuate the valves. It will be noted that the construction of the cam 31 is such that it maintains the valve 51 open throughout the greater portion of the revolution of the shaft 59, while the construction of the cam 10 is such that it permits the valve 50 to remain closed during' such period and to be opened only during the period when the valve 51 closed. such relation of the two cams being shown particularly at Fig. 9.

To actuate the cams W) and 31 and consc quently the valves 50 and 51. in proper timed relation with the valve 21 as aforesaid. a lever (12 is fulcrumed upon the shaft 5!.) and provided with a detent 63 engaging the ratchet wheel (34 with a detent (if; positioned to prevent backward movement of the ratchet and shaft.

The lever (32 is provided with a finger 66 pivoted to the extremity thereof as shown particularly at Fig. 12 in position to engage the abutment ($7 at each reciprocation of the carriage, whereby the ratchet G1 and cams (i0 and (31 are advanced a single step at each reciprocation. It will be noted that the cams (it) and (51 are duplicated so that the valves are actuated at each half revolution of the shaft 59 and it will further be noted that the ratchet M is provided with twice the number of teeth as shown upon the ratchet 42, so that the valves 50 and 51 will be actuated in timed relation with the actuation of the valve 21.

Means to control the quantity and there fore the pressure of the air delivered from the pumps 54 to the atomizers 14 is provided 'in positioning a. screw 68 in the housing of the valve 13 and in communication with the passage .37. such screw being pro vided with a tapered slot (59 so that as the screw is moved in or out the passage prtr vided by the tapered slot (39 is reduced or increased permitting the escape of air through such passage to thereby control the pressure and volume of air delivered to the atomizers as aforesaid.

It will be apparent therefore that as the carriage 10 reciprocates the lever 31- is alternately moved between the extremes of its movement, whereby, on account of the de tent 41 engaging the ratchet 42 the sleeve 43 is rotated with a step by step movement, rotating therewith the cam wheel 32 to actuate the lever 29 to open the valve 21 at the precise moment when the atomizers 12 are discharging a spray of the liquid upon the sides of the shoe. Means is therefore provided for directing the discharge of the liquid accurately upon the sides of the shoe in timed relation to the discharge of the liquid upon the top of the shoe so that the dressing is applied to all necessary iii parts of the shoe simultaneously and at such time to be properly acted upon by the cleaning and polishing mechanism not shown.

I claim:

1. In a shoe dressing applying mechanism, a stationary applier; a movable applier; and means connected with the movable applier adapted to actuate the stationary applier.

2. In a shoe dressing applying mechanism, a stationary appller; a moving part; an applier carried by the moving part; and means to actuate the stationary applier from the moving part.

3. In a shoe dressing applying mechanism, a gravity feed; a projecting feed; a

moving part; and means to transmit actuating motion simultaneously from the moving part to the feeds.

4. In a shoe dressing applying mechanism; an applier; a second applier movable relative to the first mentioned applier; means to move the second mentioned applier; and means to transmit motion from the movable applier to actuate the first men tioned applier.

In testimony whereof I ailix my signature in presence of two witnesses.
